'Prophesy' in the Bible

so that the tongues are for a sign, not to the believing, but to the unbelieving; and the prophesy is not for the unbelieving, but for the believing,

for ye are able, one by one, all to prophesy, that all may learn, and all may be exhorted,

so that, brethren, earnestly desire to prophesy, and to speak with tongues do not forbid;
